Description

  The present invention relates to a packaging container including a case and a tray accommodated in the case.

  As a container for storing confectionery or the like, a paper packaging container comprising a substantially square cylindrical case and a tray stored in the case is known.

  When the contents of such a packaging container are reduced, the container itself is larger than the contents, and the container may be disturbed for the user. For this reason, a carton that can be used by being transformed into a small container by folding the tray in half is known (see, for example, Patent Document 1).

On the other hand, in the same packaging container, the side of the tray to be pulled out is placed in the pulling out direction so that the user can easily hold it when pulling out the tray from the case. A packaging container having a space that does not contain an object is known (see, for example, Patent Document 2).

  The carton described in Patent Document 1 is suitable for storing small contents such as granulated gum. However, when such a container is used for contents such as chocolate having a large size and mass, or used for a tray having a space that does not contain the contents, such as the container described in Cited Reference 2. In some cases, when the tray is folded in approximately half and transformed into a small container, there is an inconvenience that it is not possible to secure a capacity for storing the remaining contents, such as the area taken up as the height of the small container in the tray increases. It was. Further, in the same case, there is a problem that the deformed shape cannot be held firmly and opens.

  Accordingly, an object of the present invention is a packaging container comprising a case and a substantially rectangular parallelepiped tray that is accommodated in the case and opened on one side, and when the contents are reduced, the tray is deformed to be a small container. Another object of the present invention is to provide a packaging container that can hold a deformed shape.

  The packaging container of the present invention that solves the above problems is a packaging container comprising a substantially rectangular cylindrical case and a substantially rectangular parallelepiped tray that is housed in the case so that it can be pulled out and opened on one side. The tray has a first cut line that can be cut around in the circumferential direction of the case, and the tray has a bottom face that faces the opening of the tray and a second cut line that can be cut to the side surface, and the tray By having a first fold line that can be bent substantially perpendicular to the direction in which the sheet is pulled out on the bottom surface and the side surface, the tray cuts the second cut line and folds the first fold line, thereby transforming into a small tray. It is possible.

  According to the present invention, when the contents of the tray are reduced, the second cut line of the tray is cut, and the first folding line of the tray is folded to form a small tray. Can be stored. Then, the first line of the case can be cut, and the small tray can be stored in one piece of the cut case. As described above, according to the packaging container of the present invention, when the contents are reduced, the container can be deformed in a small size, is not disturbed to carry and becomes easy to hold for the user, and deformed. The shape can be maintained.

  In the packaging container of the present invention, the length from one end of the case to the first take-out line is substantially the same as the length from one end in the direction of pulling out the tray to the first folding line, and the direction in which the small tray is drawn out The length of the tray is the length from one end in the pulling-out direction of the tray to the first folding line, and the second cut line of the tray is a direction in which the bottom surface is pulled out from the first folding line on the side surface of the tray. A position that is at least a half of the width that is substantially perpendicular to the width of the tray, and a length that is approximately the same as the width that is substantially perpendicular to the direction in which the side surface is drawn from the first folding line on the bottom surface of the tray. It is characterized by having each in the placed position.

  According to this invention, specifically, it becomes a new side surface facing the side surface in the direction in which the piece from the first fold line to the second cut line on the bottom surface is pulled out, and the piece from the first fold line to the second cut line on the two side surfaces Becomes a similar new side surface, and the shape of a small tray can be secured by fastening the two pieces on the outside of the bottom piece.

  In the packaging container of the present invention, the tray has the extension piece extending from the bottom surface, the extension piece has at least four second folding lines in the width direction, and the four second folding lines are It has a drawer part formed so that it may have a hollow part in which a section in the direction pulled out by being folded and a part of the extension piece is adhered to the bottom face is substantially rectangular.

  According to the present invention, in addition to the above-described effects, when the drawer portion of the tray is pushed from the opened side, the tray is crushed in the direction of being pulled out, so that the user of the packaging container can easily pull out the tray. Furthermore, even if the tray drawer portion is provided, the volume when the tray is deformed in a small size can be secured by adjusting the positions of the first line of the case, the second cut line of the tray, and the first folding line.

  According to the packaging container of the present invention, when the contents are reduced, the case and the tray can be deformed in a small size, and the deformed shape can be maintained.

In each of the drawings, specifically, the case 20 has a substantially rectangular tube shape having a pair of opposed openings 211 and 212, and the tray 30 is housed so that it can be pulled out from the openings 211 or 212 of the case 20. .

  The direction in which the tray 30 is pulled out is any direction (in the direction of arrow A in FIGS. 1, 2, and 4) having the openings 211 and 212 in the case 20, and is usually the longitudinal direction in the packaging container 10. In the present invention, the direction A in which the tray 30 is pulled out is referred to as the longitudinal direction, and the direction substantially perpendicular to the longitudinal direction on the bottom surface 31 of the tray 30 is referred to as the width direction.

  First, the case 20 provided in the packaging container 10 of this invention is demonstrated using FIG. 2 and FIG.

  As shown in FIG. 2, the case 20 has a substantially rectangular tube shape and has openings 211 and 212 on two opposing surfaces, and is sized to accommodate the tray 30 without excess or deficiency.

  The case 20 has a first wire 22 that makes a round in the circumferential direction of the case 20 and can be cut (see FIGS. 2 and 3). The length L1 from one end (opening 211) of the case 20 to the first line 22 is generally substantially the same as the length L2 from one end (side surface 32) in the pulling-out direction of the tray 20 described later to the first folding line 44. . Further, as described later with reference to FIG. 6A and the like, when the first wiring 22 of the case 20 is cut at all, a small case 201 having a length L1 is obtained and used for the small container 50.

  As long as the first line 22 can be easily cut by the user, the mode is not particularly limited. However, as shown in FIG. 2 and the like, cuts of about 0.5 to 10 mm are equally spaced. It is preferable that the perforations are lined up.

  Other configurations of the case 20 are not particularly limited, and a notch portion 23 as shown in FIG. 2 may be provided on the side where the tray 30 is pulled out so that the user can easily take out the tray 30. The shape of the notch 23 may be a substantially trapezoidal shape as shown in FIG. 2 or may be a shape obtained by cutting a substantially square, a substantially triangle, a circle or an ellipse, and is not particularly limited. Although not shown, the case 20 may be provided with one or more windows so that the contents of the packaging container 10 can be seen. The notch 23 and the window are provided in consideration of design and the like.

  Here, in order to obtain the case 20 shown in FIG. 2 from the blank body 29 shown in FIG. 3, for example, each fold line indicated by the broken line 24 of the blank body 29 is folded, and a piece 251 that is one end of the blank body 29 and serves as an adhesive piece Can be formed by adhering to the other end 252. In addition, the formation method of case 20 is not limited to the above-mentioned thing. Moreover, the shape of the blank body 29 is not limited to that shown in FIG. 3, and may be any shape as long as it has the above-described first line 22.

  Next, the tray 30 provided in the packaging container 10 will be described with reference to FIGS. 4 and 5.

  As shown in FIG. 4A, the tray 30 has a bottom surface 36 that faces the opening 31 and side surfaces 32, 33, 34, and 35 formed substantially perpendicular to the opening 31 (the front side surface 32 and the front side surface on the drawer side). A rear side 33 facing the front side 32, a right side 34 on the right side from the opening side toward the front side 32, and a left side 35 facing the right side 34).

  As shown in the blank body 40 of FIG. 5, the tray 30 is an extension piece extending in the longitudinal direction (the direction of being pulled out: the direction of arrow A in FIGS. 1, 2, and 4) from the bottom surface 36 facing the opened one surface 31. 37. As shown in FIGS. 4A and 4B, the extension piece 37 has a part 371 bonded to the bottom surface 36 to form a front side surface 32 on the side to be pulled out.

  4 (a), 4 (b), and 5, the extension piece 37 has at least four second folding lines 381, 382, 383, and 384 in the width direction. As shown in the cross-sectional view in FIG. 5B, the cross-section in the direction A to be pulled out is a shape having a lead-out portion 42 that is folded so as to have a hollow portion 41 that is rectangular. In this shape, when the user grasps the drawer portion 42, a force is applied as indicated by an arrow B in FIG. 4B, and the drawer portion 42 is easily crushed and held as shown by a broken line in FIG. 4B. It becomes easier to pull out the tray 30 from the case 20. In addition, the deformation | transformation aspect of the front side surface 32 is later mentioned using FIG.

  As shown in FIGS. 4A, 4B, and 5, the tray 30 has a bottom surface 36 that faces the opening 31 of the tray 30 and side surfaces 34 and 35 that are in contact with the case 30. It has a second cut line 43 that is connected and can be cut. Further, the tray 30 has a first folding line 44 on the bottom surface 36 and the side surfaces 34 and 35 that can be bent substantially perpendicularly to the direction A in which the tray 30 is drawn out. Accordingly, the tray 30 can be transformed into a small tray 301 as described later with reference to FIG. 6B and the like by cutting the second cut line 43 and folding the first folding line 44.

  Specifically, the length L1 (see FIG. 2) from one end 211 of the case 20 to the first take-out line 22 and the length L2 from one end 32 in the pulling-out direction of the tray 30 to the first folding line 44 (see FIG. 5). And the length L3 in the direction in which the small tray 301 is pulled out (see FIG. 6D) is the length L2 from one end 32 in the pulling-out direction of the tray 30 to the first folding line 44. To do. The lengths L1, L2, and L3 are appropriately set depending on the length of the drawer 42 and the size and number of contents to be put into the small container 50 when the drawer 42 is provided. The lengths L1, L2, and L3 are approximately the same as or slightly larger than or half the length L of the case 30 (see FIG. 1).

  Further, the second cut line 43 of the tray 30 is more than half of a width W1 (see FIG. 5) that is substantially perpendicular to the direction A in which the bottom surface 36 is drawn from the first folding line 44 on the side surfaces 34, 35 of the tray 30. It has a length L4 (see FIG. 5). Further, the second cut line 43 is located at a length H2 that is approximately the same as the width H1 (see FIG. 5) that is substantially perpendicular to the direction in which the side surfaces 34 and 35 are drawn from the first folding line 44 on the bottom surface 36 of the tray 30. Have. Since the first folding line 44 and the second cut line 43 are in such a positional relationship, when the tray 301 after being deformed to a small size forms a new rear side face 46 that opposes the front side face 32, the other side face is formed. It has the same height H2 as 34 and 35, and can be stored in the small case 201 without excess or deficiency.

  The second cut line 43 is not particularly limited as long as the second cut line 43 can be easily cut by the user in the same manner as the first cut line 22. It is preferable that the cuts of about 10 mm are perforations arranged at equal intervals.

  Here, the pieces 471 and 472 between the first folding line 44 and the second cut line 43 of the side surfaces 34 and 35 are fastened to form a new rear side surface 46. The mechanism for fastening is as follows. Anything may be used without any particular limitation. For example, as shown in the blank body 40 in FIG. 4A and FIG. 5, one piece 471 is provided with a cut from the upper side, and the other piece 472 is provided with a cut from the lower side, and these cuts are hooked together. Thus, both pieces 471 and 472 can be fastened. A mechanism for fastening the pieces 471 and 472 between the first folding line 44 and the second cut line 43 of the other side surfaces 34 and 35 will be described later with reference to FIG.

  5, the side surfaces 32, 33, 34, and 35 are raised by folding the side 45 of the case 30 respectively, and the rear side surface 33 has a piece 481 extending from the right side 34 and the left side 35. The front side surface 32 is sandwiched between the rear side surface 33 and the extension piece 331 and fixed by bonding or the like, and the front side surface 32 is folded so that the second fold lines 381, 382, 383 of the extension piece 37 are crested on the bottom surface 36 side. Is folded so that the bottom surface 31 side is a valley, and a part 371 on the tip side of the second folding line 384 is bonded to the inside of the bottom surface 36.

  Here, the process of deforming the case 20 and the tray 30 into a small container 50 will be described with reference to FIG.

  First, the first wiring 22 of the case 20 shown in FIG. 2 is cut to separate the two cases 201 and 202 as shown in FIG. Among these, when the cutout portion 23 is provided, the case piece 201 on the side having the cutout portion 23 is preferably used for the small container 50.

  Next, the second cut line 43 of the tray 30 shown in FIG. 4A is cut to separate the two trays 301 and 302 as shown in FIG. 6B. Among these, in the case of having the drawer portion 42, the second cut line 43 and the first folding line 44 are provided on the tray 30 so that the tray piece 301 on the side having the drawer portion 42 can be used for the small container 50. deep.

  Next, as shown in FIG. 6C, by folding the first fold line 44 of the tray piece 301, a part 473 of the bottom face 36 is raised as a new rear side face 46, and a part 471 and a left side of the right side face 34 are raised. A new rear side surface 46 is formed by folding a part 472 of the surface 35 and fastening the overlapping portions of the pieces 471 and 472. At this time, as shown in the enlarged view of the rear side surface 46 in FIG. 6C, the pieces 471 and 472 are fastened so that the tips of the pieces 471 and 472 are positioned on the front side surface 32 side of the rear side surface 46. (See FIG. 6 (c) broken line part).

  As shown in FIG. 6D, the small tray 301 on which the new rear side surface 46 is formed is housed in the small case 201 described above and can be transformed into a small container 50.

  Subsequently, a modified form of the tray 30 will be described with reference to FIGS. 7A to 7C. 7A is a perspective view of the tray 30, FIG. 7B is a blank body 40 of the tray 30, and FIG. 7C is a partial perspective view of the small container after the tray 30 is deformed.

  As shown in FIGS. 7A and 7B, the front side surface 32 of the tray 30 is formed by the extension piece 37 of the tray 30 having three second folding lines 381, 382, and 383 in the width direction. The shape has a normal edge. A piece 482 extending from the right side 34 and the left side 35 can be sandwiched between the front side 32 and the extension piece 37, and a part 371 of the extension piece 37 can be fixed by adhesion or the like. Also in this case, the tray 30 has the second cut line 43 and the first folding line 44 described above, and can be transformed into the small tray 301 and transformed into the small container 50. Although the form of the front side surface 32 is not shown, it may be the same as the form of the rear side surface 33.

  Further, the pieces 471 and 472 between the first folding line 44 and the second cut line 43 on the side surfaces 34 and 35 form a new rear side surface 46 as shown in FIGS. 7 (a) to 7 (c). It may have a mechanism to fasten. Specifically, the second cutoff line 43 that is the tip of the piece 471 is shaped so that the tip of the piece 471 is convex toward the rear side surface 33. In addition, a notch 474 that is substantially perpendicular to the direction A in which the tray 30 is pulled out is provided near the tip of the other piece 472. As shown in FIG. 7C, both the pieces 471 and 472 can be fastened by inserting the protruding tip of the above-mentioned piece 471 into the notch 474 of the piece 472. Although the shape of the tip of the piece 471 is not particularly limited, for example, as shown in FIG. preferable.
